Rescue crews first helped a person who was stuck upside hanging from a crane.
The person was reported trapped on the ride upside down around 7:55 p.m., but did not appear to be injured or in medical distress, officials said.
After that rescue, two people remain inside a box hanging from a crane stuck high above the fairgrounds for more than an hour as crews worked out a plan to get them down.
The first man attached himself to a harness and was able to lower himself down a rope to the ground.
The nature of the ride malfunction was not immediately known.
